Whether it’s moss, lichens, or algae, those unsightly green carpets and stains on your walkways, balconies, and walls can really ruin your curb appeal. But don’t worry—you don’t need harsh chemicals to get your outdoor spaces looking brand new again. Some of the best solutions are actually sitting right in your pantry!
Tackling Moss and Algae with the Same Methods
The great news is that you can get rid of moss, lichens, and algae naturally using common household staples. Two of the most effective heavy-hitters for this job are:
- Washing soda (or baking soda)
- Vinegar (or acetic acid)
Using Soda to Blast Away Moss and Algae
If you’re looking to clear green gunk off your walls, stones, or balcony, a simple mixture of washing soda and water works wonders. Start by giving the area a quick once-over to remove any large clumps of moss or lichen. Then, stir about 2 tablespoons (25 grams) of washing soda into hot water. Pour the mixture over the affected area.
Depending on how stubborn the growth is, let it sit for anywhere from a few hours to a couple of days. Once the mixture has done its job, you can easily scrub away the loosened remains. If you’re dealing with a particularly tough spot, just repeat the process until the stone is sparkling clean.
Cleaning with Vinegar
Another fantastic DIY remedy for moss and algae is vinegar. However, a quick pro-tip: stick to standard apple cider or white wine vinegar. Avoid using high-concentration vinegar essence or industrial acetic acid. Those are way too strong and can kill your nearby prize-winning flowers or even leave permanent bleach spots on your stonework.
Just like before, scrape away the worst of the moss first with a putty knife or a weeding tool. Spray the vinegar directly onto the green patches and let it soak for a few hours. Once the moss and algae have loosened their grip, give them a good scrub.
One word of caution: Vinegar isn’t a “one size fits all” solution. Keep it away from natural stone, marble, or limestone. The acid can react with these materials, leading to permanent stains and discoloration that you definitely don’t want.
Don’t Forget the Joint Sand!
Once you’ve finished cleaning out the cracks between your pavers, make sure to refill them with joint sand. This isn’t just for looks—filling those gaps properly is your best defense against moss making a comeback!
